ASELSAN A. S., the largest defense company in Turkey, initiated research activities on developing Mercury Cadmium Telluride (MCT) detectors in 2014. These research activities include bulk crystal growth and surface preparation of Cadmium Zinc Telluride (CZT) substrates, Molecular Beam Epitaxial (MBE) growth of MCT layers, MCT detector fabrication, Read-Out-Integrated-Circuit (ROIC) design and detector-dewar-cooler (DDCA) assembly development. Focal plane arrays with resolutions/pixel pitches of 320x256/30 mu m and 640x512/15 mu m are fabricated. Noise Equivalent Temperature Difference (NETD) of 320x256 FPA is 11 mK (f#/1.5, 77K) while the operability is 98.2%. 640x512 FPA provides NETD of 32 mK (f#/1.5, 77K) and the operability is 93.2%.

The improvements of the ships of opportunity program in MFS-TEP
Özsoy, Emin (Copernicus GmbH, 2007-5-23)
<jats:p>Abstract. The Ships Of Opportunity Program in the Mediterranean Sea was established at the end of 1999, in the framework of the Mediterranean Forecasting System – Pilot Project (MFS-PP). Many improvements have been made in data collection, transmission and management. Calibration of selected XBTs and a comparison of XBTs vs. CTDs during some research cruises have assured the quality of the data. Transmission now allows receiving data in full resolution by using GSM or satellite telecommunication ser...
Validation of the operational MSG-SEVIRI snow cover product over Austria
Surer, S.; Parajka, J.; Akyurek, Z. (Copernicus GmbH, 2014-2-24)
<jats:p>Abstract. The objective of this study is to evaluate the mapping accuracy of the MSG-SEVIRI operational snow cover product over Austria. The SEVIRI instrument is aboard the geostationary Meteosat Second Generation (MSG) satellite. The snow cover product provides 32 images per day, with a relatively low spatial resolution of 5 km over Austria. The mapping accuracy is examined at 178 stations with daily snow depth observations and compared with the daily MODIS-combined (Terra + Aqua) snow cover produc...

Res. 19(4):871-877. 2005.-The purpose of this study was to assess the reliability and validity of the modified Conconi test on Concept II rowing ergometers. Twenty-eight oarsmen conducted 3 performance tests on separate days. Reliability was assessed using the break point in heart rate (HR) linearity called the Conconi test (CT) and Conconi retest (CRT)...
Cytotoxicity of Hydrazones of Morpholine Bearing Mannich Bases Towards Huh7 and T47D Cell Lines and Their Effects on Mitochondrial Respiration
Kucukoglu, Kaan; GÜL, Halise İnci; GÜL, Mustafa; Atalay, Rengül; Baratli, Yosra; Geny, Bernard (Bentham Science Publishers Ltd., 2016-01-01)
N,N'-bis[1-(substitutedphenyl)-3-(morpholine-4-yl) propylidene] hydrazine dihydrochlorides, N1-N11 were designed and synthesized as cytotoxic agents. These compounds were synthesized by the reaction of 2 moles of 1-( substitutedphenyl)-3-(morpholine-4-yl)-1-propanone hydrochlorides with 1 mole of hydrazine hydrate. The compounds reported here are new, except N1 and N4. The cytotoxicity of the compounds was tested against human hepatoma (Huh7) and breast cancer (T47D) cell lines. 5-Fluorouracil (5-FU) was us...
The Pb-12(2-) and Pb-10(2-) zintl ions and the M@Pb-12(2-) and M@Pb-10(2-) cluster series where M = Ni, Pd, Pt
Nalbant Esentürk, Emren; Eichhorn, Bryan (2006-07-19)
Ethylenediamine (en) solutions of K4Pb9 react with toluene solutions of ML4 (M = Pt, Pd, L = PPh3; M = Ni, L-2 = COD) and 2,2,2-crypt to give M@Pb-12(2-) cluster anions (M = Pt (1), Pd (2), Ni (3)) as the [K(2,2,2-crypt)](+) salts in low (Ni) to good (Pt) yields. The ions have near perfect I-h point symmetry and have been characterized by X-ray diffraction, Pb-207 NMR and LDI-TOF mass spectrometry studies. For M = Ni, the primary product formed is the D-4d Ni@Pb-10(2-) cluster that has also been structurall...
